Hopeite coating on metals by the zinc phosphate chemical conversion (ZPCC) method has attracted more attention for its potential biomedical use. While the deposition ability of HA layer onto hopeite coating has been rarely reported. In this research, the hydroxyapatite (HA) layer is deposited on hopeite coating by biomimetic process. The influence of SBF concentration, immersion time and solid/liquid ratio on the layer characteristics are discussed. SBF concentration and solid/liquid ratio play vital roles in the deposition of HA layer. The deposition of HA layer is defined as three stages, the dissolution of hopeite coating, HA nucleation and growth. (C) 2016 Elsevier Ltd. All rights reserved.
